Can't argue with that although most people that have used ISF calibration seem to swear by it and usually comment on huge differences.
The equipment they use is expensive and they can access adjustment programmes on your set not available to you if the set is ISF adjustable in the first place. On my panel such a calibration will also give the option of more pre-programmed settings.
Don't get me wrong, I personally find your comment spot-on but I have a feeling I may never know what the thing can do by trying to adjust the million or so settings myself. Having spent a lot on the panel another hundred or so quid won't make any difference (I won't pay £300) so I guess I will try one of the options I mentioned myself ... then I know ... and you will too as I would be the first one to admit I've just wasted some money!
That spider calibration thing does sound reasonable value for money if it works, I'll need some more info on it. Especially as I might also go the projector route. Two ISF calibrations really start to sound a tad expensive.
I could of course just go the my dealer I bought the set from and ask the exact settings of the demonstrator which bowled me over in the first place and apply them to mine after it's run in ... na, to easy.
